@CAPS LOCK Re: Checking it out under Linux is a good idea.
"A good few people"? It will indeed in all likelihood be very few people in - in reality. Most will think, if they consider the question at all "well most of the "opposition" are equally guilty and I don't understand what Linux is." Among techies it is possible that some will take that decision. However, ordinary punters won't even consider the question - whether the "cognoscenti" like it or not. Sorry guys, the FarseBook and Twatter generation do not share your concerns.
